Sigma 50mm F2.8 EX DG Macro. Mental. I have no idea what I am doing with this thing. This is very different.

How many angels am I meant to fit on here?

Nice

I love my macro.

Mine has limited auto focus. Meaning that it is capable of focusing nearer than the limit of auto focus - so that means manually focussing for really closeup stuff.

That has led me to wanting two things:
1) a magnifier eyecup so I have a fighting chance of getting the focus right (Santa gave me one for Christmas Smile

)
2) for serious work, a focussing rail. This is like a microscope slide with a very fine screw for manually focussing in continuous and small amounts. The dof for a macro can be impossibly short, so the fine control a rail provides can help in really getting that perfect focus. And, at least with my lenses, manual focus is really a servo control for the lens auto focus motor, so it moves in steps. That makes it impossible to really fine tune the focus since it seems to always be too much or too little. A rail is on my wish list!

Have fun, can' t wait to see the pics when you know what you are doing - LOL

i love macro.. i will definitely get into it when i can get away with buying some kit for it Smile

i'll probably get some tubes and a close-up filter for my 70-200 to see what happens first though!

check out some of the stunning macro stuff that this guy takes : http://www.mdsign.nl/fotos/

he does have a tamron 90mm macro, but takes a lot of stuff with tubes and reversed primes

This is going to take a lot of practice.

Wow - what a seriously short dof! I've seen similar when using an inverted lens for closeups.

It looks very abstract. Cool Cool

Second stereo shot is awesome, don't think there is enough depth in the first one to make it stand out enough, could also be my eyes Smilie_PDT

Thanks Simon, and I agree about the first one. I have it in my little noddle to try some really serious close up stereo work today. I might try it with that watch and see what happens.

an angled shot of that watch, in stero icon_biggrin

that would be wicked me thinks. so it looks like it is coming off the page and also you get the whole hands 3d thing. I await the result...

This isn't dramatic though I think with practice I can strangle some dramatic pictures out of this lens. But it works and that's a start.

This is a little more dramatic methinks.

For any newcomers, there is a help page here for stereo viewing.

Hmmm, seems stereo viewing doesn't work with one good eye, have tried and tried and although I can get the central image, cannot get any form to it - I have a lazy eye right eye which is a pain at times as it cannot be corrected - have even tried the proverbial "jam jar"bottom lens and it don't help - and looks really strange as the other side of specs have plain lens, no magnification, so a one eyed mr magoo when they were worn some years back

creators

Curiously, I've just measured where my eyes cross to see these images, to see how extreme the cross eyed thing is. At 30 inches from the screen my eyes have to be focussed at 10 inches to see the stereo, but at that focal length, if I put my finger there, my finger is just a blur. That's just my deteriorating eyesight in old age, and yet, because I am actually focusing on an image that is 30 inches away I can still see it. Which is an enormous relief, I'd be gutted if I couldn't do them any more. Anyway, sorry you can't see them Dave, because it is quite buzzy seeing 3D in flat images.

hil26

No worries, I've become accustomed to not seeing some things as others see them, like the multicolured blob thing pictures that were all the rage a couple of years back - seems that people could see images in them.

My real concern is if something happens to my left eye, now then I would be in trouble

creators

My love affair with stereo images is all the fault of those blobby images, the first time I GOT IT, was like a bomb going off, and although those 3D images are, by comparison, crude, I shall be eternally grateful to them for kick starting a long and rewarding love affair with stereo imagery.

i couldn't get them at the beginning - doesn't help me being cross-eyed to start with tho ;)

i'm getting the hang of seeing them now, and i like the pcb one - very good Smile

i never got those pictures that were a load of coloured dots with supposedly a picture hidden in them.. there's one on the ceiling at the dentists and i can never bloody make it out!
